conductive lampblack is very useful in the production of bridgeless igniters these can be mass produced from ribbon cable.

i had purchased a 4kw diesel chinese heater . These have a drip feed pump and glow plug combustion chamber a12v fan blows hot air out for use in vehicles    etc  I was far too mean to spend money on diesel fuel so i ran it on kerosene central heating oil . after 5 hours running it stopped and would not ignite fuel.

i unbolted the combustion chamber the chamber was totally filled with about a cup full of high quality conductive lampblack i emptied the chamber into a secure jar. on reassembly the heater works well -no damage .

commercial production of conductive lampblack was from kerosene many years ago , its main use in industry today is making conductive rubber

 bridgeless igniter composition uses cmc a water based binder carboxyl methyl cellulose is found in cake shops as an additive when icing cakes if it isnt available then wall paper paste is a suitable alternative the small quantities of anti fungal present do not affect its combustion

I wonder if you've discovered a cheap way of making carbon noanotunes. Nice one.

That's awesome.  Have you tried it in lampblack stars.  I'd be really interested to see it work. I have 4 or 5 samples of lampblack.  None of them seem to be the "real mcCoy"  and I'm yet to make a true lamplack star.

hi ive not made many stars the last ones i did were using resorcinol as a binder and rolling them in plaster so they were none flammable then bound visco was inserted  into a hole in them so they were ignited in the centre they shatter showering ignited pieces across the sky. if you can pm me a postal address you can have the   lampblack  to try for star making
